Cosmology: our galaxy is an oddball (Introduction)

Dhw: Why do you declare so authoritatively that we are not dealing with an infinity of galaxies? Even in your own theistic scenario, your God is eternal, and your God makes the galaxies, so why could he not have been creating galaxies for ever and ever?

DAVID: We have no current evidence that this current universe represents an eternal universe. All the current theories either accept a beginning or a cyclical coming and going. The CMB cannot be ignored.

dhw: A cyclical coming and going allows for an eternal universe, and unless I am much mistaken, it also allows for the CMB. You seem already to have forgotten your own theory, according to which you have no doubt that your God has made many universes and there is “probably an infinity of galaxies”.

DAVID: I know what a cycle means. I'm discussing THIS universe in this possible cycle, not all the past ones. No infinity of galaxies in this one.

It makes no difference to the argument. Firstly, you have not explained why you think your God created all these individually different galaxies if his aim was to produce one that would allow life (same problem as the whale and the weaverbird’s nest, if his aim was to produce Homo sapiens). Secondly, quite apart from the fact that we don’t know if THIS universe is finite or not, you can still have an infinity of cycles and galaxies, which means that eventually there is bound to be one that can meet the requirements for life. I am not saying this is so. I am merely defending the atheist case against your theistic proposal.
